IMPROVEMENT IN MOWlNG-MACHINES.

Specification forming part of Letters Patent No. 211,946, dated February4,

1879 application filed November 7, 1878.

To all whom it may concern:

Be it known that I, ALFRED ToRN UIsT, citizen of Sweden, now residing inthe city of New York, in the county of New York and State of New York,have invented a new and useful Improvement in Mowing-Machines, of whichthe following is a specification:

The object of my invention is to provide an easy and reliable method forraising and lowering the points of the fingers for harvestingmachines,to vary the: height or angle of cut, and also to hold them in positionwhen regue lated.

The invention consists in hinging the inside shoe to a brace or arm,which arm is in turn hinged at one of its ends to one end or corner ofthe frame diagonal to the hinge of the shoe, the other end of the armextending upward and forming a handle convenient to be operated by thedriver while in the seat. It also consists in a latch and catch forfastening it when set at any desired point.

In the accompanying drawings, in which similar letters of referenceindicate like parts, Figure 1 is an end view of the machine, the inneror righthand wheel being removed. Fig. 2 is a top view of the insideshoe, the brace or arm, and a portion of the frame.

t S, Figs. 1 and 2, is the shoe. 3 is the socket Khrough which the pin 8passes, hinging .he shoe to the arm P. The arm P is hinged :30 end ofthe frame D with the pin 9, and is 7 eld to the frame by the lockingdevice 1). The arm extends back and upward and forms the \handle 19,convenient to be operated by the tlriver. R is the latch, hinged on rand r. The liatch is kept closed by the spring a. The iotches in thelatch pass over the projecting hatch 0"" on the frame. \Vhen the pointsof he fingers are to be turned the driver takes hold of the handleclasping his hand around the latch R, pressingit in toward the handle,and turns it upon the pivots r and 1", which relieves the notches fromthe catch 7". Then by pressing down or drawing up the handle the pointsof fingers are raised or lowered. When the hand releases the latch thesp'rin g causes it to catch in the notch and hold the fingers asregulated.

The lower end of the arm is connected to the frame by a diagonal hinge,9, so that when the points of the fingers are raised or lowered theposition of the knife-head in relation to the connecting-rod is notmaterially changed. It is further held opposite the upper end of theshoe-hinge by thelatch and recess 12, curved to suit the diagonal hinge9 at its lower end. m is the end of the vibrating arm which gives motionto the knife.

I claim- 1. The inner shoe of a harvesting-machine hinged to one side ofa brace or arm, which arm in turn is hinged at its lower end to one endof the frame by a hinge diagonal to the shoe-hinge, the other end of thearm extending upward and forming a handle convenient to be operated bythe driver while sitting on the machine, substantially as and for thepurpose specified.

2. In combination with the diagonal hinge 9, the latch and recess 19,for steadying the brace P, substantially as described.

3. The inner shoe of a harvesting-machine hinged to one side of a braceor arm, which arm in turn is hinged to one end of the vibrating frame bya hinge diagonal to the shoehinge and bisecting the axis thereof at ornear the pitman-joint at the heel of the cutterbar, substantially as andfor the purpose specified.
